ISLAMABAD, APR 09 (DNA): In a letter to the Interior Ministry and the Federal Investigation Agency (FIA), Islamabad police on Monday sought a travel ban on the United States diplomat involved in a fatal road accident.

The police swung into action after reports emerged that US Defence Attache Colonel Joseph might leave the country. Police also requested the Interior Ministry to keep a check on the movement of the US diplomat.

According to a statement, the Foreign Ministry said that “justice will take its course” in accordance with local and international laws.

It said Hale expressed his sympathy and sadness over the loss of life and assured cooperation in the investigation.
